Peerless Arcana

This feat, as a boon from lord Santa himself, allows Bannette to learn any spell (in scroll form) that she can find and can apply them into her spellbook , at the same cost as the spellbook cost per level writing.
Spell casters can write out spell scrolls and Bannette can transcribe ANY spell into her book.

She gains advantage, and expertise on arcana checks.
